Title: Wobble tube evaporator with whip rod fluid distributor
Inventor: YAO TZU LI
IPC: B01D3/00
Filed: 1985-04-04
Abstract: An evaporation or distillation apparatus uses a tube driven to wobble about a vertical axis aligned with the tube. A distributor supplies a fluid to the inner surface of the tube at its upper end. A flexible whip rod located at least in part within the tube slides around over the inner surface as the tube wobbles and spreads the incoming fluid stream into a thin film having a uniform thickness over the length of the tube. Preferably the rod is anchored at its lower end to a stationary base and is restrained against rotation about its own longitudinal axis, but is flexible at its lower end to act as a universal joint. A distributor may be mounted on the container above the tube to distribute fluid to the tube using the centrifugal force of the wobbling motion. Alternatively the rod is hollow and conducts the fluid to its upper end where the motion of the rod distributes the fluid to the inner surface of the tube. <IMAGE>

IPC: A01G31/00
Filed: 1985-08-20
Abstract: Plant carrying devices with a cylindrically formed wrapper 2a, which surrounds a body of filling material and possibly a seed. The filling material (3) contains artificially produced foam particles or consists of the latter. Also described is a method for producing such devices by continuously supplying at 21 a wrapping material strip 2, by continuously supplying filling material from 11 and possibly seeds from 16 to the wrapping material strip. The filling material is removed from a supply and its individual particles are spread out continuously to form a thin layer, the height of which is low in comparison to the width at right angles to the conveying direction. The filling material of the fleece is accumulated at 14 to form a narrow filling material rod, which is delivered at right angles to the conveying direction of the fleece and in the direction of its own longitudinal axis, wrapped at 24 by the wrapping material strip and thus made to form a continuous tubular plant carrying device, from which the plant carrying devices are cut off at 28. Apparatus for carrying out this method is also described. <IMAGE>

Title: Vestigial sideband amplitude modulated transmission system with additional data capacity
Inventor: CORPORATION BRITISH BROADCASTI
IPC: H04J9/00
Filed: 1988-06-10
Abstract: An adaptive zero synchronous phase modulation system comprises a vestigial sideband amplitude modulated (VSB- AM) television transmitter and coder means responsive to a further data signal to introduce phase or frequency modulation of the amplitude modulated carrier of the transmitter, wherein this modulation is effected by a process of complex conjugation at the complex zeros of the amplitude modulated signals such as to select members of a common envelope set which all possess the same envelope and bandwidth but have different phase functions. In order to permit satisfactory vestigial sideband operation the following steps (a) to (d) are implemented:   (a) the modulation is effected in a channel of bandwidth less than or equal to the double sideband component of the VSB-AM signal, (b) the rate of complex conjugation is varied in an inverse relationship to the AM picture information content, (c) the coder means signals ahead information related to the data rate established by step (b), (d) a further NICAM carrier for stereo sound is modulated in sympathy with the modulation of the first said carrier. v

Title: Waveguide coupling arrangement
Inventor: HOWARD KEVIN RICHARD
IPC: H01P1/17
Filed: 1989-06-16
Abstract: A capacitively coupled printed patch (3) as a high efficiency device to couple orthogonally polarised energy between a stripline (5) and a waveguide (1). Coupling between the stripline (5) and the patch (3) is achieved by the stripline terminating in a narrow strip probe (4), the end of which lies close to, but not in contact with, an edge of the patch (3). Two separate probes (4) arranged mutually orthogonally are used to effect independent polarised couplings to produce independent linear orthogonal signals or independent left- and right-handed circularly polarised signals. The striplines (5) and patch (3) are supported on a common substrate (8) which extends transversely through the waveguide (1). The waveguide wall has a quarter-wavelength thickness (T) so that its inner edge (10) appears continuous to energy passing through the substrate (8). One application is in a DBS satellite TV receiving system where it is required to isolate two signals sharing a common channel but having orthogonal polarisations.
